FAQ Frequently Asked Questions

What is Base64 encoding used for?
Base64 encoding converts images into text strings that can be embedded directly in HTML, CSS, or code. This reduces HTTP requests, works in offline applications, and allows storing images in databases as text.
Which image formats are supported?
The converter supports JPG, PNG, GIF, WebP, and other common web image formats. Each format maintains its original quality and characteristics in the Base64 output.
Are my images uploaded to any server?
No, all conversion happens locally in your browser. Your images never leave your device, ensuring complete privacy for sensitive images like documents, personal photos, or confidential materials.
What is the size limit for images?
While there is no strict limit, very large images create very long Base64 strings that may be impractical to use. For web use, keep images under 1MB for reasonable Base64 string lengths.
Can I use the Base64 output directly in HTML?
Yes, the tool generates complete data URI strings (data:image/jpeg;base64,...) that can be used directly in HTML img tags, CSS background images, or anywhere a URL is expected.
